In a pocket the LC9 fits better. It's just a little bit smaller, smoother and lighter than the Shield. I haven't tried the PPS but it's about the same as the Shield.
No safety on the PPS. I'll keep the LC9 for the time being. Too bad S&W didn't make it a tad smaller than the LC9, trigger is much better than the LC9. I don't have a big problem with the Ruger trigger, I shoot better rapid fire with it than I do with a 642 revolver.
